Form 8858 Balance Sheet and Section 987 for a Business Abroad

Do I need Form 8858 with a balance sheet for my business abroad?

Form 8858 is required of a US person who is directly the tax owner of a foreign disregarded entity (the person treated as owning its assets and liabilities for US tax) or who operates a foreign branch at any time in the year. The instructions call this a Category 1 filer and require the whole form, including the balance sheet (Schedule F) and the separate Schedule M for related-party dealings. Owning through tiers of disregarded entities (Category 2) requires it too. A US person includes a citizen, a resident, and a domestic corporation, partnership or trust.

The form is due with the return it belongs to, including extensions. Publication 54 lists it among the forms filed with Form 1040, and for an electronically filed Form 1040 the instructions say to attach it to Form 8453. With an electronically filed Form 1120 it goes in electronically as an attachment.

A foreign branch is an integral business operation a US person carries on outside the United States, decided on all the facts; a separate set of books and an office or fixed place of business abroad are evidence of one, and activities that are a permanent establishment under a US tax treaty are deemed one (section 1.367(a)-6T). Whether your business is a branch, a disregarded entity, a corporation or a partnership decides which form applies; see which form your foreign business files, which also covers a shorter filing for a dormant disregarded entity.

The case is not simple when:

• The business keeps books only in local currency or a local format.
• Several years are unfiled. Each year's balance sheet starts from the prior year's close.
• Money has moved from the business to you, which can bring in Section 987 (currency gain or loss on money sent to its owner).
• A corporation owns the branch, or the branch deals with other companies you control.

If one of these applies, get the books in order before the form is started.

Gather these before anyone prepares the form:

• Ledgers or exports for each year, in any language. The form must be in English, so local-language records need translating.
• Statements for every business bank account.
• The purchase date and cost of each major asset.
• Every transfer between you and the business, dated, in both currencies.
• The prior year's balance sheet, foreign tax returns and the source of your exchange rates.
• The ownership chain with each entity's country and tax classification, for the organizational chart the form requires.
• Who holds the books and where, and the entity's US tax ID, or the reference ID number you assign and reuse each year.

What does Form 8858 ask for: income statement, balance sheet and taxable income?

Form 8858 asks for a summary income statement, a summary balance sheet and a taxable income schedule for the branch or entity. Most schedules show its functional currency (the main currency it operates in, defined below) and US dollars; the balance sheet is in dollars only (form).

Schedule F has only six lines, but in practice they come from a full set of books. Its start-of-year column normally equals the prior year's end-of-year column.

Does the Form 8858 balance sheet have to follow US GAAP?

Yes: the instructions have the filer figure the Form 8858 balance sheet in the entity's functional currency and translate it into dollars in accordance with US GAAP. The income statement follows US GAAP too. The exception is a business that must use the dollar approximate separate transactions method (DASTM) for a hyperinflationary currency: it prepares Schedule F under section 1.985-3(d) rather than US GAAP, with special rules on Schedules C and H.

The instructions do not require the business to keep its ledger under US GAAP. They require US GAAP figures on the form, so a ledger kept under local rules needs a restatement before it reaches Schedule F. A preparer decides which differences matter.

Which exchange rates translate the figures: average rate or year-end rate?

Each schedule has its own rule. The yearly average rate covers the taxable-income line on Schedule H and Schedule M. US GAAP translation rules cover the income statement and the balance sheet, and the form names no single rate for the balance sheet. Section 987 measures the business's net value on the last day of the year.

Form 8858 reports each rate as the units of foreign currency that equal one US dollar, to at least four places, and the foreign amount is divided by it (instructions). The IRS has no official rate. It generally accepts any posted rate used consistently and publishes yearly average rates for many currencies. For Section 987, any reasonable averaging method is allowed, and one consistent with the business's financial accounting is generally presumed reasonable (section 1.987-1). Record the source and method each year.

What is my functional currency: the dollar or the local currency?

An individual's functional currency is the dollar (section 985). A business abroad can have another only if it is a qualified business unit (QBU) and passes the tests in section 1.985-1. A QBU is a separate and clearly identified unit of a trade or business that keeps separate books and records (section 989).

The business's functional currency is the dollar if any of these is true:

• It conducts its activities primarily in dollars.
• Its residence is the United States, which for a business unit means its principal place of business is there (section 1.985-1, section 988).
• It does not keep books in the currency of the economic environment where a significant part of its activities takes place. The regulation presumes it does, and only a substantial nontax reason overcomes that presumption. A business cannot use the presumption to support its own choice.
• Its income is effectively connected with a US trade or business.
• Its currency is hyperinflationary, which the regulation defines by cumulative inflation over the prior 36 months. Its income is then figured under DASTM.

Otherwise it is the currency of the environment where a significant part of the business is conducted, provided its books are kept in that currency. The regulation looks at the currencies of revenues, expenses, cash flows, borrowing, sales markets and pricing. If more than one currency fits, the business may choose.

A functional currency is a method of accounting, and a later change must follow section 1.985-4 (section 1.985-1). Line 1j of Form 8858 takes the three-letter ISO currency code. If the functional currency is the dollar, only the dollar column of Schedule C is completed.

What does Section 987 do, and when does it create a gain or loss?

Section 987 recognizes the currency gain or loss that has built up on a business abroad's net value, in proportion to the money it sends back to its owner, when the business's currency differs from the owner's. The statute treats the gain or loss as ordinary (section 987). The regulations work in four steps:

1. Each year the owner tracks the business's net value in the owner's currency. The year's change, adjusted for income and for transfers in and out, is that year's unrecognized gain or loss. These amounts accumulate (section 1.987-4).
2. Nothing is recognized until a remittance, except on a termination (step 4) or under an election to recognize every year. A remittance is the value moved from the business to the owner, minus the value the owner moved into the business, in the same year. It is measured in the business's currency on the last day of the year (section 1.987-5). The regulation counts all cash and other assets transferred to the owner and sets no condition on where they go.
3. The gain or loss recognized is the net unrecognized amount at year end times the remittance proportion: the remittance divided by the year-end adjusted basis of the business's gross assets plus the remittance. A loss can be suspended instead (see the elections below).
4. Ending the business counts as a remittance of all its gross assets, so the proportion is one.

Net value uses two rates: the year-end spot rate for cash, receivables and payables in the business's currency, and the historic rate for items such as equipment. The historic rate is the yearly average for the year the asset was acquired (section 1.987-1). Purchase dates in the books make that possible.

The regulations also offer elections, such as translating the whole net value at the year-end rate (a current rate election) or recognizing gain or loss every year. A current rate election can suspend a Section 987 loss instead of allowing it (section 1.987-11). The US owner makes these elections on Form 8964-ELE, attached to the timely original return, extensions included, for the first year the rules apply to the owner. For a later year, a current rate or annual recognition election must also be e-Faxed before the year starts. Both are hard to undo (instructions, section 1.987-1). Decide with a preparer before the year starts.

Notice 2026-17 is not a regulation: it announces proposed rules. It lets a taxpayer rely on a simpler equity and basis pool method, which needs a current rate election, and on narrower loss suspension, if the rules are applied together (IRS).

Gain or loss is reported on Schedule C-1, with a statement of the method (instructions).

Do the Section 987 rules apply to me, and from which tax year?

The Section 987 rules apply when the business is a qualified business unit (QBU) whose functional currency differs from its owner's. The final regulations apply to tax years beginning after December 31, 2024 (section 1.987-15).

Any individual or corporation can be the owner, except individuals who are not US persons and certain foreign corporations. Partnerships and S corporations have separate rules in section 1.987-7, which section 1.987-1 points to. If the business and its owner both use the dollar, Section 987 does not apply, and the instructions do not require Schedule C-1 for that owner.

Earlier years follow different rules, and a business that existed before the final regulations started may pass through the transition rules in section 1.987-10. An owner holding such a business on the transition date, generally the first day of the first year beginning after 2024, also files Form 8964-TRA with the return for that year (instructions). A small business can elect to treat its earlier gain or loss as zero if it meets the section 163(j)(3) test and an asset-size limit (section 1.987-10). Which set applies to each year of a catch-up depends on the filing history and needs a preparer (section 1.987-15).

Do I need separate books for the business abroad?

Form 8858 and the Section 987 records are built from books kept for the business alone, so keep a separate set. The law defines a business unit by its separate books and records. The instructions say a separate set of books, or the lack of one, "may affect" whether an activity is a foreign branch (instructions). Whether an activity without its own books is a branch depends on the facts, so do not assume missing books mean no form.

A separate set of books means books of original entry plus general and subsidiary ledger accounts, or similar records (section 1.989(a)-1). On the cash method the entries include a journal of every receipt and payment; on the accrual method, journals of sales and of expenses. The ledger accounts show how those entries affect the balance sheet and the income statement.

A ledger in the currency the business operates in, with its own bank account to reconcile against, is the base for both. Books kept in a different currency can make the dollar its functional currency, subject to the books presumption described above.

For a business subject to Section 987, section 1.987-9 requires records that establish its taxable income or loss and its gain or loss each year, kept as long as they may matter. They include:

• Income, gain, deduction and loss items, in the business's currency and the owner's.
• An adjusted balance sheet in both currencies. Section 987 works from a tax-basis balance sheet, while Schedule F is a US GAAP one.
• The exchange rates used, and how any convention was chosen.
• Amounts moved to and from the owner in both currencies, and each year's remittance and running totals.

What goes on Schedule M for money moving between me and the business?

Transfers between you and your own branch generally do not go on Schedule M. Schedule M reports transactions with other related entities. If you are the tax owner, the filer column (b) stays empty, and disregarded transactions with the direct US tax owner are left out of column (c) (instructions). When Section 987 applies, money moving between you and the business is tracked as a remittance on Schedule C-1 instead.

Schedule M covers sales and purchases, commissions, rents, royalties, dividends, interest and loan guarantee fees. A branch that buys goods from a corporation you control belongs here. Loans are shown as the largest balance outstanding during the year, and amounts are in dollars at the year's average rate.

What is the penalty if Form 8858 is late or incomplete?

The instructions set a penalty of $10,000 for each annual accounting period of each controlled foreign corporation or controlled foreign partnership for which the required information is not furnished on time. If the failure continues 90 days after the IRS mails a notice, a further $10,000 applies for each 30-day period or fraction, limited to $50,000 for each failure. Foreign taxes available for credit are also reduced by 10% for failing to file or report all the required information, with more after a notice.

Those sentences are worded for controlled foreign corporations and partnerships. The statute's dollar penalty covers a "foreign business entity", defined as a foreign corporation or a foreign partnership (section 6038), and the IRS penalty manual lists Form 8858 under the same penalty (IRM 20.1.9). How it reaches an individual's own branch or disregarded entity is a question to put to a preparer before a form is late. The manual allows reasonable-cause relief from the initial penalty, not the continuation penalty. By statute, though, the due date and the start of the 90-day notice period count as no earlier than the last day reasonable cause existed (section 6038(c)(4)(B)), so check the cause and the notice date before accepting a continuation penalty.

The instructions add that criminal penalties under sections 7203, 7206 and 7207 may apply to a failure to file the information section 6038 requires. A person who has someone else file Form 8858 can face these penalties too if the other person does not file a correct and proper form. A missing foreign information return can also keep the related tax year open for assessment until three years after the information is furnished, or only the related items if reasonable cause applies (section 6501(c)(8)), covered in Form 5471, 8858 or 8865.

Is Form 8858 doable on my own?

Sometimes: the form is four pages plus Schedule M, and the books and the currency work take the time.

The instructions may be enough when all of these are true:

• There is one branch or entity, with nothing below it.
• The books are in one currency and agree with the bank statements.
• The business and its owner use the same functional currency, the dollar for most individuals.
• Every earlier year is filed.

A business with another functional currency falls under Section 987, which still asks for yearly records and Schedule C-1 in a year with no transfers.

Professional judgment is needed when:

• The books are in a local format, are not reconciled, or exist only in another language.
• The functional currency differs from yours, whether or not money has moved.
• Several years of Form 8858 are unfiled.
• A corporation, partnership or S corporation owns the branch, or the currency is hyperinflationary.

Example

These examples are illustrative. Local amounts are in Mexican pesos or Canadian dollars as stated, the dollar figures are in US dollars, and the exchange rate and asset basis are invented.

A design studio in Mexico with books in pesos

A US citizen runs a design studio in Mexico as a sole proprietor and keeps separate books in pesos. For the year, revenue is 1,800,000 pesos and costs are 1,080,000 pesos. The studio keeps no US GAAP statements in dollars, so she uses an average rate of 18 pesos per US$1, checks the average-rate box on Form 8858's Schedule C and reports 18.0000 on its Schedule H, line 8. That Schedule C shows US$100,000 of revenue, US$60,000 of costs and US$40,000 of profit beside the peso figures. A real filing uses a posted rate, such as the IRS yearly average, applied the same way every year.

A US corporation with a branch in Canada

A US corporation operates a branch in Canada and keeps its books in Canadian dollars. Schedule F needs a six-line summary balance sheet in US dollars at the start and end of the year, translated under US GAAP rules, not a spreadsheet of Canadian-dollar totals. If the branch's functional currency is the Canadian dollar, it differs from the corporation's, so Section 987 applies and Schedule C-1 is completed.

Money moves home in December

The same Mexico owner, whose studio has the peso as its functional currency, moves 360,000 pesos from the studio account to her US account in December and has put nothing into the studio during the year. That is a remittance of 360,000 pesos, measured on the last day of the year. If no election applies and the final regulations govern the year, the regulation's formula divides the remittance by the year-end adjusted basis of the studio's gross assets plus the remittance. With a basis of 1,140,000 pesos, that share is 360,000 divided by 1,500,000, or 24%, applied to the studio's net unrecognized Section 987 gain or loss. That amount comes from the year-by-year net value computation, not from comparing what 360,000 pesos was worth in January and in December. Running that computation is the part that needs a preparer.

Different for you?

• You are not sure the business is a branch or a disregarded entity: the test is in which form your foreign business files.
• You own shares in a company abroad: Form 5471 may apply; see US owners of foreign companies, books for a small foreign company and, for a Canadian corporation, its books as Form 5471 statements.
• Local-language or local-format books cannot produce a balance sheet, or the ledger does not match the bank statements: the books come first, then the form. See bookkeeping help and, for the form, cross-border tax help.
• Several years of Form 8858 are unfiled: each year's balance sheet starts from the prior year's close, so the books are rebuilt in order. See catching up on missed foreign reporting, streamlined or delinquent filing and cross-border tax help.
• Money has moved from the business to you and Section 987 may apply: the method, the elections (Form 8964-ELE), any transition filing (Form 8964-TRA) and the Schedule C-1 statement call for cross-border tax help.
• A corporation owns the branch, or the branch deals with companies you control: Schedule M reports those dealings and Section 987 applies when the currencies differ, so get cross-border tax help.
• A partnership or S corporation owns the branch: a US partner may have to file part of Form 8858, including Schedule C-1, when the partner rather than the partnership recognizes Section 987 gain, and Section 987 follows separate rules for both, so get cross-border tax help.
• The business pays foreign income tax: the credit and its limits are in foreign tax credit limits.
• You are choosing a structure while living abroad: see LLC or S corporation while living abroad.
• The business has accounts abroad: an individual's are in foreign account reporting and a company's in FBAR for company accounts abroad.
